Davis says voting documents altered after filibuster

Sen. Wendy Davis told CNN’s Anderson Cooper that a fellow senator was informed by a Capitol staff member that the official voting documents had been purposefully changed to falsify the time of the vote on SB 5, the bill killed in her dramatic Tuesday night filibuster.

The discovery was important, she said, because had the vote been stamped on 6/25, rather than 6/26, the bill would have passed.

“We know it was purposeful,” she said. “I think there will be further investigation.”

Early Wednesday, Sen. Juan Hinojosa distributed two documents — the first showing that the bill passed on 6/26, the second appeared on Texas Legislature Online nine minutes later, with the date 6/25.
